IMPROVEMENT IN SPINDLES FOR SPINNING.

Specification forming part of Letters Patent No. 35,145, dated May 6,1862,

To all whom it may concern.-

Be it known that I, JAMES EATON, of Boston, in the county of Suffolk andState of Massachusetts, have invented certain Improvements in Spindlesfor Spinning, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, makingpart of this speciication, in which- Figure 1 is one of my improvedspindles with a partially-formed cop thereon; Figs. 2, 3, and 4, detailsto be referred to.

In spinning with the ordinary spindle, with its blunt or rounded endover which the thread slips as the twist is being put in, the thread issubjected to a series of vibrations caused bythe slipping at shortintervals of the thread over or oft from the end of the spindle. Thesevibrations not only interfere with the regular drawing ol the threadfrom the roving and cause the thread to draw harder at one instant thanat another, and render it more liable to break, but the twist is not putin by a continuous regular operation, but by an intermittent one,whereby the thread is not spun so smooth and uniform as is desirable.Another objection to these vibrations is that the many small fiberswhich may be observed standing out from the surtace of the thread, andwhich should be twisted in with it, are thrown off and wasted, iillingthe room with dust. To obviate these vibrations is the object of mypresent invention, which consists in so forming the point of the spindlethat the thread will draw from the axis of the spindle.

That others skilled in the art may understand and use my invention, Iwill proceed to describe the manner in which I have carried it out.

In the said drawings, A, Figs. l and 2, is the spindle, the top end ofwhich is so formed that when it is revolved in the direction of thearrow, Fig. 2, and the thread a is drawn in the usual direction when.spinning, which is nearly horizontal, as shown in the drawings, thethread will be carried in by the grooves and inclines into the centralopening, c, while when the thread is drawn up vertically after beingthrown or drawn out from the opening c (as when the pieceris drawing itott) it will render oit freely from the outer surface of the spindlewithout the necessity of stopping the spindle. There are various formswhich may be given to the point of the spindle to accomplish theseends-without departing from the spirit 'of my invention.

I have shown in Figs. l and 2 the end of the spindle formed in a scroll,the part 5 ofwhich projects so as throw the thread, when heldvertically, off from the center, and as the spindle is revolving rapidlyin the direction ofthe arrow the thread will pass from the portion 5 tothe portion 6 without falling into the opening or slit between the point7 and the shoulder S; but when the thread a is inclined, as shown inred, it will fall 011 the incline 9 and draw up under the point 7 intothe central opening, c. In Fig. 3 the same end is accomplished byreducing the size of the scroll, leaving a shoulder, h, immediatelybeneath it, which, when the thread is held up vertically, keeps it outbeyond the inclines l0 and ll and prevents it from running into thescroll; but when the thread is lowered, as in Fig. 2, it is at oncecarried into the scroll and drawn from the axis ot the spindle. It isquite desirable that this provision be made for drawing off the threadvertically, as otherwise thepieeer would have to stop the spindle whenhe4 wished to tie a broken thread. The form shown in. Fig. it will notaccomplish this, as the thread falls onto the incline 12 and is led intothe scroll.

Among other advantages of this improved center-draft spindle I maymention that it requires less power to operate, as the thread, beingkept at an equal tension by drawing all the time from one point on thespindle,

set forth.
